I have been using PayPal for last few years but hardly notice any user interface improvements. There are many alternative Payment processing services but nothing comes close to PayPal’s universal presence. While some are good, they are best only for the US market. So, if there is ever a PayPal 2.0, I wish it has the following features:

Keep the font color black in a white background. Any other color combination can be painful for the reader’s eyes and challenge those who are color blind. If you still wish to have colored fonts, choose a dark font in a light background with sufficient contrast and ask some of your friends for opinion. Do not use blue color for font as it may be confused with a link. Do not write the post using multiple colored fonts. If you want to highlight a point, use quotes, bold, italic formats.

Text Formatting

Use Bold, Italic styles only when needed and not very often. Do not underline unless it is a link.

Scripts, Gadgets

Do not fill your blog with too many gadgets, scripts. Your readers may not die if you remove some but it will help load the page faster for them. If an external site serving script for your blog goes down, it will cripple your blog too. So keep only the most important scripts.

Browser, OS, Resolution compatibility

Check your site in popular browsers and operating systems and in all screen resolutions. Your check list should have Firefox, Safari, Linux for sure. Your main post content should be completely visible in 800×600 screen resolution.
